FAIRHAVEN — Fairhaven's water supply is being chlorinated after tests this week revealed total coliform.

"Low levels were detected in both water towers," Water Superintendent Edward Fortin said. "We will flush and chlorinate the system."

He said the positive tests were taken Tuesday.

Another round were taken on Friday but results won't known for several days.

Total coliform is a collection of relatively harmless micro-organisms that live in large numbers in the intestines of humans and warm and cold-blooded animals. It doesn't pose a public health threat, Mr. Fortin said.

It is distinct from the far more dangerous fecal coliform, or E. coli bacteria, which was not detected in the tests.

Only people in higher-risk groups, such as those with compromised immune systems, should consult a physician before drinking town water.

Officials began putting chlorine into well sites Thursday night. The water towers were chlorinated Friday, Mr. Fortin said.

There were no current plans to drain the towers, nor is a boil order warranted.

Mr. Fortin said the state Department of Environmental Protection has been informed about the tests.

Officials plan to conduct a series of tests next week to confirm the system is free of total coliform.

Mr. Fortin said chlorination may leave a small taste and smell in the water.

Total coliform has been detected several times in the town's water system in the past. Last December, officials were forced to drain the Sconticut Neck water tower after total coliform was detected twice in less than a year.
